Traffic density around the globe is increasing on a day-to-day basis, resulting in more accidents, congestion, and pollution. The dynamic vehicular environment induces challenges in designing an efficient and reliable protocol for communication. Timely delivery of safety and non-safety messages is necessary for traffic congestion control and for avoiding road mishaps. For efficient resource sharing and optimized channel utilization, the media access control (MAC) protocol plays a vital role. An efficient MAC protocol design can provide fair channel access and can delay constraint safety message dissemination, improving road safety. This paper reviews the applications, characteristics, and challenges faced in the design of MAC protocols. A classification of the MAC protocol is presented based on contention mechanisms and channel access. The classification based on contention is oriented as contention-based, contention-free, and hybrid, whereas the classification based on channel access is categorized as distributed, centralized, cluster-based, cooperative, token-based, and random access. These are further sub-classified as single-channel and multi-channel, based on the type of channel resources they utilize. This paper gives an analysis of the objectives, mechanisms, advantages/disadvantages, and simulators used in specified protocols. Finally, the paper concludes with a discussion on the future scope and open challenges for improving the MAC protocol design.

The transformation and upgrading of the industrial manufacturing field brings important development opportunities for the promotion and deployment of the Industrial Internet of Things (IIoT). How to connect huge number of IIoT nodes to the current IP-based Internet for promoting the integration of industrialization and informationization is a key issue towards IIoT. Targeting at the insufficiency that existing algorithms only support a single channel and utilize limited number of time slots, which results in the deteriorated performance for solving the problem of resource allocation for nodes with different priorities. In this paper the self-similarity of the observation data of the IIoT nodes is evaluated to dynamically prioritize the nodes, and then Deep Q Network (DQN) algorithm is adopted to design an adaptive resource allocation method that takes into account the characteristics of diverse node priorities. Simulation results demonstrate that the proposed method can effectively improve network throughput and reduce data transmission delay in comparison with existing methods. INDEX TERMS Industrial Internet of Things, deep Q network, resource allocation, priority.
